Patterns of cellular phone use among young people in 12 countries: Implications for RF exposure

Abstract

Overview

The Mobi-Expo study investigates the characteristics and determinants of cellular phone use among 534 young individuals aged 10-24 in 12 different countries, focusing on exposure to radiofrequency (RF) fields during childhood and adolescence, which is crucial for assessing health risks.

Findings

• Phone use behaviors such as the number and duration of calls significantly vary based on gender, age, and social status.
• The study reports higher phone use in females and in older age groups, with variability also influenced by the country of origin.
• Use patterns of SMS and wireless data also show significant differences, indicating evolving technology use over time.

Conclusion

Results underline substantial international differences in phone usage, which are important for designing future health studies and strategies to mitigate RF exposure risks. The study's limitations due to its convenience sample nature are also acknowledged, highlighting the need for broader research to confirm these findings.
